Improving condensing performance of a low-cost floating solar still by surface characteristic alteration

This work focuses on improving the performance of floating solar still by varying wettability and contact angle hysteresis of the cover surface. Static and dynamic characteristics of droplets on transparent PVC sheet and anti-fog film are measured and applied on a floating solar still prototype. The experimental result shows that wettability is insignificant to transmissivity and absorber temperature since the static contact angles for PVC (44.86°) and anti-fog (13.71°) are below the contact angle critical value (48.63°). However, low contact angle hysteresis found in the anti-fog film promotes the first sliding cycle phenomenon to occur and hence increases the water collection by 33.18%. To assess the quality of the distilled water for domestic use, a heterotrophic plate count (HPC) analysis was also conducted, showing a lower amount of microbial content in the distilled water. These findings can be further considered as a guideline in designing high-performance floating solar still.

Effectiveness and durability assessment, under extreme environmental conditions, of a superhydrophobic coating applied onto sandstone from Carteia roman archaeological site

Superhydrophobic coatings have been often used to protect stone surfaces against water. The durability of these coatings has been rarely tested for monumental heritage exposed to outdoor conditions. In this work, a highly effective superhydrophobic nanomaterial has been applied in the archaeological site of Carteia, which is located next to the sea and an industrial area. The effectiveness and durability of this nanomaterial have been evaluated in the laboratory and after one year of in situ exposure and compared against two specific commercial products. The results revealed that the product prepared in our laboratory exhibited high consolidant and superhydrophobic effectiveness, high static contact angle and low contact angle hysteresis. After one year, our product effectiveness was maintained due to the uniform coating with 4 mm depth penetration. The consolidant and hydrophobic commercial products presented reduced protection, with cracked coatings and poor penetration into the sandstone structure.

Reactive silver inks for antiviral, repellent medical textiles with ultrasonic bleach washing durability compared to silver nanoparticles.

Medical textiles are subject to particularly harsh disinfection procedures in healthcare settings where exposure risks are high. This work demonstrates a fabric treatment consisting of a reactive silver ink and low surface energy PDMS polymer that provides for superhydrophobicity and antiviral properties against enveloped herpes simplex virus stocks even after extended ultrasonic bleach washing. The antiviral properties of reactive silver ink has not been previously reported or compared with silver nanoparticles. The fabric treatment exhibits high static contact angles and low contact angle hysteresis with water, even after 300 minutes of ultrasonic bleach washing. Similarly, after this bleach washing treatment, the fabric treatment shows reductions of infectious virus quantities by about 2 logs compared to controls for enveloped viruses. The use of silver ink provides for better antiviral efficacy and durability compared to silver nanoparticles due to the use of reactive ionic silver, which demonstrates more conformal coverage of fabric microfibers and better adhesion. This study provides insights for improving the wash durability of antiviral silver fabric treatments and demonstrates a bleach wash durable, repellent antiviral treatment for reusable, functional personal protective equipment applications.

Super-omniphobic surface prepared from a multicomponent coating of fluoro-containing polymer and silica nanoparticles

A multicomponent superomniphobic coating that can be applied to a broad range of substrates via simple spraying of a hybrid material system consisting of fluorinated poly[dimethylsiloxane-co-(3-aminopropyl) methylsiloxane (PDMS-F), fluorinated silica nanoparticles (FSiO2-NPs), and perfluoroalkyl polymer (F-Polymer). The PDMS-F was prepared by reacting the aminopropyl-containing copolymer of PDMS linear tridecafluoroheptanoic acid and branched heptafluoroisobutyrate respectively to yield the fluorinated polymer, named PDMS-NF and PDMS-BF respectively. By sequential spraying of PDMS-NF, FSiO2-NPs, and F-Polymer, the three-component omniphobic coating produces surface with lower contact angle hysteresis (CAH) (<15°) for most liquids, including water, hexadecane, glycol, ethanol, and diiodomethane, regardless of their polarity or surface tension. It can be applied on different substrates including fabrics, especially the cotton textile, which exhibits a static water contact angle (CA) of 163° and hexadecane (oil) CA of 153°.

Smooth Transparent Omniphobic Coatings with Remarkable Liquid Repellence

AbstractLiquid repellent surfaces are of high interest in various fields like protective coatings and droplet manipulation due to their outstanding properties from self‐cleaning to anti‐fouling. Most reported surfaces rely on the fabrication of micro/‐nanostructured surfaces, the infusion of porous surfaces with immiscible lubricants, or the grafting of monolayers with low surface energy to achieve repellence of various liquids. However, these methods are limited in terms of their durability and long‐term stability. Here, the fabrication of smooth, transparent fluorinated poly (perfluoroalkyl methacrylate) coatings via UV‐initiated radical polymerization in a simple one‐step procedure is reported. The resulting surfaces show very low surface energies of down to 7 mN m−1, low contact angle hysteresis below 5°, very good repellence towards various liquids with different polarities as well as self‐cleaning and anti‐graffiti ability. The fabricated coatings can be applied to various substrates from glass slides to microfiber cloths. This demonstrates that they outperform common commercially available fluorinated coatings, such as, for example, Hyflon AD 40L S, in terms of liquid repellence and their performance in real‐world applications.

Multi-liquid repellent, fluorine-free, heat stable SLIPS via layer-by-layer assembly

Slippery liquid-infused porous surfaces (SLIPS) are an emerging class of bio-inspired materials attracting researchers due to their good anti-fouling, anti-icing, and self-cleaning performance. The fluorinated lubricants which are used in the preparation of multi-liquid repellent SLIPS are not suitable for practical applications because of the lubricant losses by evaporation and water drop cloaking and also they cause environmental and health problems. In this study, layer-by-layer (LbL) assembly technique via a capping approach is used to obtain PDMS-based SLIPSs. Amino terminated PDMS was used as a homofunctional polymer layer and three different copolymers of anhydride [poly(ethylene-alt-maleic anhydride) PEMA, poly(isobutylene-alt-maleic anhydride) PIMA and poly(maleic anhydride-alt-1-octadecene) PMAO] were used as the capping layers to give LbL layers having advancing contact angles between 115° and 120° with the change of the type of anhydride copolymer used and the constituent concentration. Silicone oil was used as the lubricant giving a fluorine-free LbL-SLIPS having a contact angle hysteresis as low as 5–6° repelling water and various other liquids such as glycerol, ketchup and soy sauce by preserving the low contact angle hysteresis for long durations. Moreover, LbL-SLIPS samples also had good heat resistance (to 80 °C for 8 days) and chemical stability against acids and bases and were durable under the flow of continuous water droplets for a period of 4 h without any damage to SLIPS properties. The best performing LbL-SLIPS sample was prepared using the PEMA capping layer where the decrease in silicone oil thickness and increase in contact angle hystresis were found to be lowest under continuous water droplet flow after 4 h.

Turning hierarchically micro-/nanostructured polypropylene surfaces robustly superhydrophobic via tailoring contact line density of mushroom-shaped nanostructure

The Cassie–Baxter equation is not always applied to all heterogeneous surfaces for explaining superhydrophobic phenomena. A two-step anodization method combining with a microstructure (MS) imprinting process is used to prepare anodized aluminum oxide (AAO) templates with mushroom-shaped nanostructure (NS) and micro-/nanostructure (MNS). Polypropylene surfaces with single-tier architecture (i.e., NS or MS) and hierarchical structure (i.e., MNS) are replicated using AAO templates by compression molding. The key to improving hydrophobicity of single-tier architecture is increasing contact line density (ρcl). Data fitting shows that the relationship between ρcl and contact angle (CA) is a sophisticatedly exponential curve. By tuning the diameter and array density of NS, the optimized NS replica achieves a CA of 163.7° and roll-off angle of 0.9°. Further, the optimized MNS replica possessing low CA hysteresis of 0.2° and surface adhesion force of 4 μN achieves a relative reduction of energy loss by 7% compared with NS replica.

Reducing the contact time of impacting water drops on superhydrophobic surfaces by liquid-like coatings

Surfaces that can rapidly shed impacting drops are important for a wide range of applications, including anti-icing, dropwise condensation and miniaturized drones. Previous strategies to reduce the contact time of impacting drops are primarily based on engineering superhydrophobic surfaces through introducing secondary textures, either macroscopic or nanoscopic, or constructing specifically designed nanotextures. Here, a facile and effective approach is demonstrated to reduce the contact time of superhydrophobic surfaces by simply replacing the widely used perfluorosilane (i.e., trichloro (1H, 1H, 2H, 2H-perfluorooctyl) silane, PFOS) coating with liquid-like perfluorinated polyether (PFPE) surface chemistry. Though their apparent contact angles are comparable, the PFPE-coated superhydrophobic surface exhibits a reduction of contact time up to 26% compared to the PFOS-coated counterpart, attributed to enhanced retraction speed on the former surface. Remarkably, while a classical inertial model predicts a merely 3% difference in retraction time between the PFPE- and the PFOS-coated surfaces, a drastic reduction of retraction time by 12–32% is observed. The improved retraction dynamics on the liquid-like surface is suggested to be caused by the low contact angle hysteresis and enhanced interface slippage on the liquid-like coating. This study offers a general strategy to enhance dynamic liquid repellency of superhydrophobic surfaces for diverse applications.

Robust silane self-assembled monolayer coatings on plasma-engineered copper surfaces promoting dropwise condensation

Dropwise condensation is well known to result in better heat transfer performance owing to efficient condensate/droplet removal, which can be harnessed in various industrial heat/mass transfer applications such as power generation and conversion, water harvesting/desalination, and electronics thermal management. The key to enhancing condensation via the dropwise mode is thin low surface energy coatings (<100 nm) with low contact angle hysteresis. Ultrathin (<5 nm) silane self-assembled monolayers (or SAMs) have been widely studied to promote dropwise condensation due to their minimal thermal resistance and scalable integration processes. Such thin coatings typically degrade within an hour during condensation of water vapor. After coating failure, water vapor condensation transitions to the inefficient filmwise mode with poor heat transfer performance. We enhance silane SAM quality and durability during water vapor condensation on copper compared to state-of-the-art silane coatings on metal surfaces. We achieve this via (i) surface polishing to sub-10 nm levels, (ii) pure oxygen plasma surface treatment, and (iii) silane coating integration with the copper substrate in an anhydrous/moisture-free environment. The resulting silane SAM has low contact angle hysteresis (≈20°) and promotes efficient dropwise condensation of water for >360 hours without any visible sign of coating failure/degradation in the absence of non-condensable gases. We further demonstrate enhanced heat transfer performance (≈5-7× increase over filmwise condensation) over an extended period of time. Surface characterization data post-condensation leads us to propose that in the absence of non-condensable gases in the vapor environment, the silane SAM degrades due to reduction and subsequent dissolution of copper oxide at the oligomer-substrate interface. The experiments also indicate that the magnitude of surface subcooling (or condensation rate) affects the rate of coating degradation. This work identifies a pathway to durable dropwise promoter coatings that will enable efficient heat transfer in industrial applications.

Droplet Spreading Characteristics on Ultra-Slippery Solid Hydrophilic Surfaces with Ultra-Low Contact Angle Hysteresis

Dynamic interactions of the droplet impact on a solid surface are essential to many emerging applications, such as electronics cooling, ink-jet printing, water harvesting/collection, anti-frosting/icing, and microfluidic and biomedical device applications. Despite extensive studies on the kinematic features of the droplet impact on a surface over the last two decades, the spreading characteristics of the droplet impact on a solid hydrophilic surface with ultra-low contact angle hysteresis are unclear. This paper clarifies the specific role of the contact angle and contact angle hysteresis at each stage of the droplet impact and spreading process. The spreading characteristics of the droplet impact on an ultra-slippery hydrophilic solid surface are systematically compared with those on plain hydrophilic, hydroxylated hydrophilic, and plain hydrophobic surfaces. The results reveal that the maximum spreading factor (βmax) of impacting droplets is mainly dependent on the contact angle and We. βmax increases with the increase in We and the decrease in the contact angle. Low contact angle hysteresis can decrease the time required to reach the maximum spreading diameter and the time interval during which the maximum spreading diameter is maintained when the contact angles are similar. Moreover, the effect of the surface inclination angle on the spreading and slipping dynamics of impacting droplets is investigated. With the increase in the inclination angle and We, the gliding distance of the impacting droplet becomes longer. Ultra-low contact angle hysteresis enables an impacting droplet to slip continuously on the ultra-slippery hydrophilic surface without being pinned to the surface. The findings of this work not only show the important role of the surface wettability in droplet spreading characteristics but also present a pathway to controlling the dynamic interactions of impacting droplets with ultra-slippery hydrophilic surfaces.

One-step fabrication of superhydrophobic nanocomposite with superior anticorrosion performance

Superhydrophobic coatings having a self-cleaning ability and anticorrosion performance are desired in many industrial contexts; however, high costs and complex fabrication methods limit their application. In this study, thin anticorrosive superhydrophobic coatings were prepared by a scalable, simple, and inexpensive spraying method to protect AA2024-T3 surfaces. The two-component coatings were designed using fluoropolyurethane and varying concentrations of surface modified silica nanoparticles. Surface characterization was performed using contact angle and contact angle hysteresis measurements, field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectrum (EDS), and atomic force microscopy (AFM) techniques. Corrosion protection, water uptake, and adhesion strength of the coatings were evaluated by electrochemical impedance spectroscopy (EIS) and cross-cut tests, respectively. Increased silica nanoparticle concentrations up to 10 wt% led to increased contact angles from 92° to 167°. The lowest contact angle hysteresis was obtained for the coating containing 4 wt% nanoparticles. FE-SEM images showed that high concentrations of nanoparticles (more than 4 wt%) led to cracks in the coating surface. The best performance of a coating was observed when the coating contained 4 wt% nanosilica particles, resulting in a 164° water contact angle, almost 60 days of surface protection, an impedance value of 2.2 × 109 Ω·cm2, 0.9% water uptake, and marked adhesion strength. The impedance value of the coating with 4 wt% nanosilica particles was about 25× that of the blank sample.

Altering the Surface Properties of Metal Alloys Utilizing Facile and Ecological Methods.

The development of a superhydrophobic and, even, water-repellent metal alloy surface is reported utilizing a simple, fast, and economical way that requires minimum demands on the necessary equipment and/or methods used. The procedure involves an initial irradiation of the metallic specimen using a femtosecond laser, which results in a randomly roughened surface, that is subsequently followed by placing the item in an environment under moderate vacuum (pressure 10-2 mbar) and/or under low-temperature heating (at temperatures below 120 °C). The effects of both temperature and low pressure on the surface properties (water contact angle and contact angle hysteresis) are investigated and surfaces with similar superhydrophobicity are obtained in both cases; however, a significant difference concerning their water-repellent ability is obtained. The surfaces that remained under vacuum were water-repellent, exhibiting very high values of contact angle with a very low contact angle hysteresis, whereas the surfaces, which underwent thermal processing, exhibited superhydrophobicity with high water adhesion, where water droplets did not roll off even after a significant inclination of the surface. The kinetics of the development of superhydrophobic behavior was investigated as well. The findings were understood when the surface roughness characteristics were considered together with the chemical composition of the surface.

Mechanisms of dropwise condensation on aluminum coated surfaces

Dropwise condensation (DWC) is a complex phase-change phenomenon involving the formation of randomly distributed droplets on the condensing surface. The promotion of DWC instead of the traditional filmwise condensation (FWC) is a promising solution to enhance the efficiency of heat exchangers by increasing the condensation heat transfer coefficient. The interaction between the condensing fluid and the surface (wettability) is important in defining the condensation mode. On metallic surfaces widely employed in heat transfer applications, the condensing process occurs in filmwise mode. Ideally, an engineered surface designed to achieve high DWC heat transfer coefficients should present low contact angle hysteresis and low thermal resistance. Among the different available techniques to modify the surface wettability, hybrid organic-inorganic sol-gel silica coatings functionalized with hydrophobic moieties (phenyl or methyl groups) have been identified as a feasible solution to promote DWC on metallic surfaces. In the present paper, different aluminum sol-gel coated surfaces have been tested during DWC of steam in saturated conditions. The realized coatings have been characterized by means of dynamic contact angles and coating thickness measurements. Condensation tests have been performed using a two-phase thermosyphon loop operating in steady-state conditions that allows visualization of the condensation process and simultaneous heat transfer measurements. Heat transfer coefficients have been measured by varying the heat flux, at 106 °C saturation temperature and with vapor velocity equal to 2.7 m s−1. A high-speed camera is used for the visualization of the DWC process.

Crosslinking inert liquidlike polydimethylsiloxane brushes using bis-diazirine chemical insertion for enhanced mechanical durability

Inert polymer brushes offer excellent omniphobic and antifouling properties but enhancing their durability remains a challenge, since their chemical inertness also means they lack the functionality necessary for traditional crosslinking reactions. We report the crosslinking of nanoscale polydimethylsiloxane (PDMS) brushes on surfaces through a chemically non-destructive C–H insertion. bis-Diazirine crosslinkers are employed to covalently link methyl groups (i.e., insertion into Si–C–H bonds) along neighboring PDMS chains upon thermal activation. The successful crosslinking of PDMS brushes is evidenced directly by X-ray photoelectron spectroscopy analysis and indirectly through mechanical durability characterization using Martindale abrasion. The apparent contact angles and low contact angle hysteresis of crosslinked PDMS brushes are well-maintained post abrasion, indicating enhanced mechanical durability as compared to uncrosslinked brushes. The longevity of the liquidlike character of crosslinked PDMS brushes is also improved following mechanical wear, with a shear ice adhesion strength half that of uncrosslinked brush surfaces. The crosslinked surfaces are also resistant to acid corrosion, heating, sonication, and tape peeling, indicating that the physicochemical stability of PDMS brushes is not degraded upon crosslinking. Finally, crosslinked brushes are additionally deposited on polycarbonate substrates, and the optical transparency, enhanced durability, and droplet shedding capability of the coated substrates are demonstrated. Overall, this study provides a new pathway for the design of durable inert nanoscale coatings that maintain their attractive surface properties after mechanical wear.

Liquid-solid triboelectric nanogenerators for a wide operation window based on slippery lubricant-infused surfaces (SLIPS)

Triboelectric nanogenerators (TENG) have emerged as suitable devices that are suitable to harvest widely abundant and renewable blue energy. However, a major drawback in related deployments include the reliability of the system when operating in variable atmospheric conditions. To address this limitation, we propose the integration of slippery lubricant-infused porous surfaces (SLIPS) as key TENG component. For instance, we combine SLIPS with transistor-inspired architectures to develop a robust single-electrode triboelectric nanogenerator (SLIPS-SE-TENG) that is shown to operate effectively under extreme temperature and humidity. For this purpose, we use the energy of water droplets (as in rain) impacting a surface to generate the electrical energy output. Our theoretical calculations and atomic force microscopy measurements show that a small volume of lubricant per surface area (4 μL/ per cm2 of porous PTFE) is sufficient to produce a low water contact angle hysteresis, leading to efficient energy conversion, provided the droplet’s moving velocity on the surface surpasses a threshold (0.3 mm/s). As such, we demonstrate SLIPS-SE-TENG to generate an instantaneous short-circuit current of 3 μA (charge density 8.8 nC/cm2). Importantly, we address the limitations of TENG fabricated with traditional superhydrophobic surfaces, affording a device that works normally and stably in harsh environments, under freezing temperatures or high humidity.

Toward Surfaces with Droplet Impact Robustness and Low Contact Angle Hysteresis

AbstractSuperhydrophobic surfaces show excellent water repellent performance. However, liquid impalement occurs when a droplet impacts on the surface at high velocity. To achieve higher resistance to liquid impalement at the same scale, a dense array of structures or structures with pinning at the structures top are typically used, but they also lead to increased contact angle hysteresis and higher energy dissipation. Changing the structure side wall shape can help to maintain low hysteresis and withstand high impact energy at the same scale. Droplet contact angle, contact angle hysteresis and droplet impact experiments are performed on both conical and cylindrical pillar surfaces. Comparing conical and cylindrical pillar structures with the same pitch and height, it is found that cylindrical pillars exhibit higher critical Weber number but result in larger contact angle hysteresis and larger liquid residue size when above a critical Weber number. A proper design of conical structures can maintain large contact angle, low hysteresis, strong resistance to impalement, higher number of bouncing and smaller liquid residue size. In addition, the critical Weber number for the conical structures in this work is higher than micro‐patterned pillar surfaces at the same pitch range, implying that we improve the anti‐wetting performance further.

Polydimethylsiloxane‐Silane Synergy enables Dropwise Condensation of Low Surface Tension Liquids

AbstractDespite decades of research on promoting the dropwise condensation of steam, achieving dropwise condensation of low surface tension liquids remains a challenge. The few coatings reported to promote dropwise condensation of low surface tension liquids either require complex fabrication methods, are substrate dependent or have poor scalability. Here, the rational development of a coating, which is applicable to all conventionally used condenser metals, is presented by combining a low contact angle hysteresis polydimethylsiloxane with a low surface energy silane using atmospheric vapor phase deposition. The siloxane‐silane coating enables the dropwise condensation of fluids with surface tensions as low as 15 mN m−1 in pure vapor conditions. This siloxane‐silane coating enables a 274%, 347%, and 636% heat transfer enhancement during ethanol, hexane, and pentane condensation, respectively, when compared to filmwise condensation on the same un‐coated surfaces. Furthermore, this coating exhibits 15 days of steady dropwise condensation with no apparent signs of coating degradation. This study not only demonstrates the possibility of achieving stable dropwise condensation of low surface tension fluids on scalable, structure‐less surfaces, it also develops design principles for creating facile, substrate‐independent, durable, and scalable omniphobic coatings for a plethora of applications.

Study of Micro- and Nanopatterned Aluminum Surfaces Using Different Microfabrication Processes for Water Management.

Superhydrophobic surfaces demonstrate extreme water-repellence, promoting drop-wise over film-wise condensation, increasing liquid mobility, and reducing thermal resistance for heat-exchanger applications. Introducing topographic structures can lead to modified surface free energy, as inspired by natural systems like the lotus leaf, potentially allowing coating-free ice- and frost-free surfaces under certain conditions. This work presents a study of coating-free aluminum micro/nanopatterns fabricated using micromilling or laser-etching techniques and the resultant wetting properties. Our review and experiments clarify the roles of line-edge-roughness and microstructural geometry from each microfabrication technique, which manifests in technique-specific nano- to midmicro-scale roughness, producing a hierarchical structure in both cases. For micromilling, line-edge-roughness consists of jagged burrs of 1-8 μm thickness with 10-25 μm periodicity along the microlines with constantly changing height on the order of 1-20 μm. These effects simultaneously raise the water contact angle from 52° (unprocessed aluminum) up to 136° but with strong edge pinning effects. On the other hand, laser-etched surfaces exhibit line-edge-roughness with a microstructure of 3-20 μm width and 5-10 μm in height superimposed with evenly spread spikes of 50-250 nm. This results in a high contact angle (>150°) coupled with a low contact angle hysteresis (<15°), promoting superhydrophobicity on a coating-free aluminum surface. It is also shown that for certain cases, line-edge-roughness is more important for the resultant wetting properties than the structure geometry.

Simultaneous water reclamation and nutrient recovery of aquaculture wastewater using membrane distillation

A large amount of aquaculture wastewater with high load of nutrients, organic matter, and microalgae will pollute receiving water body and needs to treat before discharge. In this work, membrane distillation (MD) with the ability to avoid non-volatile substances was used to purify water and simultaneously recover nutrients from aquaculture wastewater. Results showed that micro-structures have evenly distributed on the surface of polyvinylidene fluoride (PVDF) membrane using nylon taffeta substrate. Resultant membrane has surpassed superhydrophobicity benchmark. It achieved high water contact angle of 153.3° and low contact angle hysteresis of 8.4°. The continuous separation and treatment of fish farm wastewater showed a small and steady flux reduction of 1.4 kg/m2·h, indicating less fouling by the surface-printed membrane. In the batch process of feed concentration, the water recovery reached 86.3%. The retentate concentration of fish farm water is at least five times higher than initial concentration of ammonia (16.4 to 82.2 mg/L), phosphate (18.0 to 99.8 mg/L), and potassium (68.0 to 384.8 mg/L). This concentrated feed can use as primary nutrient of liquid fertilizer. In feed concentration process, except for ammonia (>86%), rejection of all selected inorganic substances is higher than 99%.

Icephobic and Anticorrosion Coatings Deposited by Electrospinning on Aluminum Alloys for Aerospace Applications.

Anti-icing or passive strategies have undergone a remarkable growth in importance as a complement for the de-icing approaches or active methods. As a result, many efforts for developing icephobic surfaces have been mostly dedicated to apply superhydrophobic coatings. Recently, a different type of ice-repellent structure based on slippery liquid-infused porous surfaces (SLIPS) has attracted increasing attention for being a simple and effective passive ice protection in a wide range of application areas, especially for the prevention of ice formation on aircrafts. In this work, the electrospinning technique has been used for the deposition of PVDF-HFP coatings on samples of the aeronautical alloy AA7075 by using a thickness control system based on the identification of the proper combination of process parameters such as the flow rate and applied voltage. In addition, the influence of the experimental conditions on the nanofiber properties is evaluated in terms of surface morphology, wettability, corrosion resistance, and optical transmittance. The experimental results showed an improvement in the micro/nanoscale structure, which optimizes the superhydrophobic and anticorrosive behavior due to the air trapped inside the nanotextured surface. In addition, once the best coating was selected, centrifugal ice adhesion tests (CAT) were carried out for two types of icing conditions (glaze and rime) simulated in an ice wind tunnel (IWT) on both as-deposited and liquid-infused coatings (SLIPs). The liquid-infused coatings showed a low water adhesion (low contact angle hysteresis) and low ice adhesion strength, reducing the ice adhesion four times with respect to PTFE (a well-known low-ice-adhesion material used as a reference).
